The present invention relates to shuttle checks for vlooms and has for its principal b-' ject to provide a device of this character adapted to engage the picker stick iri'friction gripping relation whereby to check the shuttle as the same is thrown into the shuttle b0x., a

A further object of the invention is to pro- .vide means for releasing the shuttle check from engagement with the picker'stick to permit the return stroke thereof, said releasing action being controlled by .a releasing rod disposedin a position for actuation by the crank arm of the loom. V v A still further object of the invention is to provide a pair of yicldably mounted check shoes arranged in frict-im gripping relation-with the opposite sides of the picker stick of the loom at the period of operation of the loom when the shuttleis thrown into the shuttle box thereof and including means for adjusting the shoes in spaced relation with respect to each other and in alinement with the path of travel not ce-id picker stick.

An additional object is to provide a device of this character of a simple and practical construction, is strong and durable ef-" and. reliable in per'fiormance, relitively inexpensive to niasiufacture and install in operative position and otherwise well adapted to the, purposes 01 which the some is iii-- end d. i

Other objects and advantages reside in the special construction, combination and ar-,

rangenient oi the various elements forming the inv'en-tion as more fully'hereinafter dcscribed and claimed, reference had to: the accompanying drawings forming part hereof, wherein like numerals refer to like 40 parts throughout, and in which: 7

The area Within the sections 5 undo issufiiciently large to permit the normal movement of the picker stick 7 of'a loom of conventional construction as shown generally at check shoes 11 having'wthcir opposer faces provided with a layer friction material 12, one end of cachet said shoes being freely ,moimted upon a bolt 13 extemiing transversely between sides of therigid' section 5 and at a position thereon ad'acent the closed end of said said b0 having sr pair of coil springs 14 arranged thereon and disposed between the 8ideothesedtion 53nd one of the shoes 11 whereby ,tofieldably A spacin member 15 is interposed the shoes list the endthereef rovided with the bolt 13', said spacing meni er being of a U-shaped formation as clearly iHustratied in Figure 3 of the drawing with one end disposed between the shoes 11 and its opposite end disposed against the inner face of the end 16 of the section 5, a

The POI-tibll of /the spacing. member 15 disposedagainst the end 16 is formed with,

a longitudi extended slotted opening 1": within which a bolt 18 is adjusmhly fitted,

' formed in the end lflof the section 5,. the

outerendof: the bolt carrying a nut 20 where with respect to each other. 7

' From this construction it will be understood that the member-15m: be and justed transversely with respect to t sides of the section 5 of the shuttle died: so that the check shoes 11 may be evenly spaced with respect to the path of movement of the I picker stick for engaging the opposite edges thereof.

- with one end of the bolt inserted through a.

vby to secure the parts in adjusted position 7 ends of the shoes 11 are spaced apartv a dis ,tance slightly less than the width of the picker stick so that the picker stick may free-' v lyenter thedivorging end of the shoes until Each oithc check shoes ll carries a laterally extending stud 21 which extends'outwardly through an opening in the adjacent side of the section 5 each of said studs-having a coil spring 22 arranged thereon and interposed between the shoe andthe side of said sections for yieldably urging the ends of the shoe remote from the bolt13 in a direction toward each other.

The outer ends of each oi'the studs 21' may carry suitabie tension'adjusting means for the snring which may be in the form ot a .L L.& J c, j p Q nut 23threaded on the outer end 01 the stud or the like.

' One of the brake shoes 11 is also provided with a laterally extending p n 24 extending through an opening in the side 01" the section ,5 adjacent thereto, the outer end of said pin being provided with a collar 25 secured thereto by meansof a set screw 26. v The collar 25 is spaced suliiciontly from the outer face of the side of the section 5 so as to permit one end of a releasing rod 27 to be, interposed between the collar and the side of the section .5, said releasing rod being arranged in the form of. a crank with its intermediate section V -rotatably supported in brackets 28 attached to the loom frame and with its end remote from the pin 2 1, disposed substantially at right angles to the intermediate section oi the rod as shown at 29 and operatively engaged bya pin 30 adjustably carried in. a bracketSl mounted along the upper edge of the crank arm 10 of the loom.

Provision is also made for the longitudinal adjustment of the sections 5 and 6 of the shuttle check by means of a longitudinally extending slotted opening 32 formed in one end of the section ,6 through which a bolt 33 is inserted for attaching to the adjacent end of the section 5, the adjustment of the slotted end of the section 6 thus permitting an adjustment between-the respective ends of the check. f

It will be noted from an inspection of Figure 2 of the drawings that the ends of the shoes 11 remote from the spacing member15 arearrangcd at a diverging angle with respect to each other and normally spaced apart adistance slightlygreater than the width of the picker stick; The opposite the opposite sidesofthe picker stick engage the inner faces of the shoe whereupon'the movement of the picker stick will be 'checked and the same will furthermore be engaged in friction gripplng' relation by reason of the friction material 1 2 andfthroughthe action of the respective springs lit and 22.

WVith the shuttle check arranged in a position with respect to the loom as shown in Figure 1 of the drawings, it will be appar- 'until the shuttle is further actuated for its return movement. Consequently the in- 'ward movement of the shuttle will also be checked by this checkingofthe picker stick. This return movement of the shuttle and picker stick coincide with the vertical movement of the crank arm 10 of the loom in a predetermined manner and as the crank arm 10 is actuated the releasing rod 27'accordingly moves the pin 2i outwardly so as to release the picker stick from engagement with the check tube 11. The throw or the picker stick toward the section 6 or the shuttle check is then permitted, the resiliency ot the material from which the section 6 is constructed permitting the striking of the picker stick therein so as to check the movement thereof without causing. injury to the same, and also prevent the picker stick from striking other parts;

It is obvious that my invention is susceptible to various changes and modifications in construction without departing from the spirit of the invention or the scope of the appended claims, and I accordingly claim all such forms of the device to which I am entitled. I

Having thus described my invention, what I claim as new is:

1. In combination, a loom having a picker stick'with a shuttleand crank arms operatively associated therewith, and check means for the shuttle arranged for engaging the pickeristick whereby to check the movement of shuttle'thereot in one direction and releasing means for the check means operable through said crank arm.

2. In combination, a loom having a picker "stick with a shuttle and crank arms operathrough said crank arm,'said check means.

comprising a pair of spaced check shoes adapted for frictionally' engaging the opposite side of the picker stick.

3.
